I have an older Legend (s/n: D002552) and have been using it via PS/2 KVM switch without issue for years. Today I replaced my old DB15/PS2 based KVM with a new Gefen DVI/USB one. I therefore opened up the Legend and swapped the cable so the PS/2 connection is internal and the USB external. I rebooted the PC and ... "unrecognized USB device". The keyboard DOES light up, but ... any time I hit a key, I gt the error balloon and no letter on the screen.

I plugged my 82 key Deck (s/n: D003399) into the new KVM and the PC recognizes it instantly.

Do I have a problem with the Legend? Do I need to send it in for service? Is there something I need to do other than merely swap which end of the cable is connected inside the keyboard case? Or what would you suggest?

You may also want to check with the KVM manufacturer as sone limit the current that can be output through the KVM. Your Deck Legend will draw up to 498mA and some KVM's can't handle that much power. Chances are if the lights come on yours is fine and you do just need to clip the resistor located in the top left corner and labeled with silkscreen printing (W3 if I remember correctly but I don't have one in front of me right now).

Thanks for the suggestion. I pinged their tech support and the response was that the KVM in question can handle 500mA. And it's working nicely for me, so you may want to note for your customers that the Gefen 2x1 DVI KVM Switcher (supports DVI up to 1920x1200, USB2.0 & audio) can be counted among those that support the legend!
